G1 Black screen, Cannot get to bootloader

Hey, I have been given a phone off a friend to fix but it wont turn on. Booting normally, I get a vibration and then the backlight comes on but i cannot see anything. When i try to boot into the bootloader by holding the camera button and powering it on, the backlight comes on but nothing else. I cannot see the bootloader. Under both circumstances, I cannot turn the phone off. I have to pull the battery to turn it off.
Does anyone have any suggestions about a possible fix? Thanks

Havie you tried send when trying to enter bootloader? If it resets then you can still get to bootloader. If not, your friend has soft bricked and only way is to JTAG which takes strong hardware knowledge and steady hands.

ok im having the exact same problem. actually i thought it was a battery problem so i spent 77$ on a 3700 mAh new batter i guess tripple life... and got it yesterday booted gave same problems. black screen where T-Mobile should be yet the rom loads with scribble screen meaning u see part but it looks like the pixels are messed up. so actually decided to resort to what someone told me a Factory Reset so Pressing Camera + Power i got a Black Backlight screen yet wont show... and I cant turn it off without Taking out the Battery this has become a issue after installing cyanogen 5.0.7 T5... since then i Re-rom'd to superbad 1.2.5 same problem screen scribbles and stops im thinking did I fry it i dont even know how to google my problem because its pretty unique it isnt a battery issue its something in the hardware ... or am I wrong please send us some feedback... ill keep this thread in mind

Sorry, what do you mean by 'send'. I am a complete noob when it comes to G1's. I have worked out i can shut off the phone by holding call + menu + end but thats it. I still cannot see anything at all on the screen. I still only get a vibration on boot. How would I know if the boot has been sucessful but i simply cannot see?
Could the flex ribbon cable be nackered?

Screen stays black! Audio and touch are responding.

Hi all,
I woke up this morning and my note's screen hasn't been working. I didn't drop it or spill anything on it, it just doesn't turn on. I know the phone is on because i can hear and see the capacitive buttons light up when i touch them. Does this mean i need to replace the Super AMOLED/digitizer unit?
The only thing i can see is the white Samsung logo (very faintly at that) when its booting up.
I found a site that sells replacement units but i don't want to buy it unless i have to.
I need some advice.

Hey thanks for the reply. But i my phone is not even rooted. it was working fine last night.. the only thing i did different was i didn't charge it over night. So i thought at first it was a battery issue. I'm so sad... lol

sounds like the backlight is burnt out... unfortunately this is not something that can be replaced itself... the digitizer/lcd will need replaced. now is the fun part... either find the country your note is made for and mail it to the warranty dept, or have it fixed by a reputable repair shop out of warranty...

No need to have root, to go to stock recovery
Just switch off device, keep holding vol up + Home + Power
when light turns, release power button, but keep holding other two.
If you able to enter in recovery, N can read on screen, means screen is intact.
wipe cache, wipe data
N still error remains, flash Stock ROM

[Q] Lumia 1520 Screen Died

My screen went out on my 1520. I cant shut it off and have txt and voxer messages coming in. Backup is on but not sure how often it runs. Any way to force a backup before I activate the new phone that comes tomorrow?

R u sure that the screen is really dead? Have u tried soft reseting the phone? If not, I advise u to do so. Hold down volume down and power for about 15-20 secs, until the phone vibrates. Then see what happens. Either way, ig the phone is comming, u r in a win-win situation.

i think u need to do a factory reset
sound like a firmware problem
what firmware are u on

Mine does some blinks when i'm getting in or out of the always on screen display mode, but not everytime. got it in more than 1 rom.

I don't have such issues on my SE.

[/COLOR]Dang it. I'm experiencing the same issue for the past few days with my Global ver. Mi8.
Any solutions?

Change to default theme

This
Installed "dark mod" miui theme today and this resulted in a white strobe light screen after the first unlock attempt... No way to stop it's or access anything.
Slight panic since I'd seen threads about this issue and assumed it's hardware problem
Only way to stop it was a forced power off by long press of the power button.
Luckily on next boot the screen was working and I was able to Uninstall the theme again

Just when I was about to go to the service centre today, my phone becomes normal. Not sure why though.
How about you guys phone?

And the problem has reappeared? I have had the same problem and from one day to the next it has been "fixed". I was going to process the guarantee ...
